Abstract

A method for the manufacture of a support construction for the coil ends in an electrical machine. According to the method, hollow objects substantially filled with a powdery filler agent and provided with porous walls are placed into the winding before its impregnation. The air spaces in said hollow objects are substantially filled in connection with the impregnation such that said objects, after hardening of the impregnation agent, constitute strong and rigid cast-plastics components.
